Lord Lucan: Was mystery man living in Lord Lucan murder house?

The man could have been a boyfriend of one of the women in the property where Sandra Rivett was bludgeoned to death in 1974.

A MYSTERY man may have been living in the house where Lord Lucan’s nanny was murdered, according to a sensational new claim.

The man could have been a boyfriend of one of the women in the property where Sandra Rivett was bludgeoned to death in 1974.

The report would back up Lucan’s claim, which he made in letters posted after he disappeared, that he disturbed an “intruder” at the murder scene. But Lucan’s son last night expressed anger at the new revelations.

A BBC documentary tomorrow is expected to say researchers have unearthed a witness statement which they claim was not shown at the inquest into Sandra’s death.

In it, Lucan’s late sister-in-law Lady Sarah Gibbs claimed to have had a conversation with the peer’s daughter Camilla, then four. The child ­apparently suggested a man was living at the London house where her mother Veronica, brother George and sister Frances also lived.

The girl is said to have implied the man could have been a boyfriend of her mother, who had split from Lucan. But Lady Sarah is believed to have said the man was more likely to be ­Sandra’s boyfriend.

The researchers are also understood to have found two police reports that Lucan was alive in 2002. Son George Bingham, 45, said last night: “If there is new evidence that is credible and from serving police officers, all well and good. But I very much doubt there is. We have been very clear with the BBC that we do not agree with what they are saying and we do not believe their claims.”

The family also insist this is the first time they’ve heard of the alleged conversation between Lady Sarah and Camilla. Last night the BBC said: “BBC Inside Out South East has uncovered more evidence surrounding the disappearance of Lord Lucan and the murder of Sandra Rivett.”
